Appl. No.:

12/154264

Inventors:

Jeno Muthiah - Wayne IL, US
Gerald K. White - Amelia Island FL, US
Duane R. Rubash - Antioch IL, US

International Classification:

A01G 25/00
B32B 1/08

US Classification:

428357, 428 341, 428 342, 428 357, 428 359, 428 369

Abstract:

The invention provides processes for coating the surface of substrates such as a sheet, film, foam, fiber, etc. , with a curable liquid resin or solution of curable resin, then in one embodiment, stably attaching a superabsorbent polymeric powder to such resin, and then curing the resin to form a coated superabsorbent product. Such substrates may include polymeric materials. Other process embodiments utilizing curable and thermoplastic resinous powders may be used instead of curable liquid resins and resulting products are included in the invention. The coated product may be utilized for water and nutrient retention in combination with irrigation, erosion control, to direct plant root growth, and to clean up standing water and petroleum spills.

Abstract:

A method of underground watering utilizes a pouch-like container product made by joining a first sheet having SAP particles adhered to a first surface with a second sheet to form a container partially filled with such particles. The application of pressure, for example by passing the product through a roll nip, facilitates joining of the sheets and causes the particles to break through at least the one of the sheets to create an opening whereby free volume is created to permit the particles to expand when in contact with a liquid. The resultant product is used to collect, store, and dispense water-containing liquids into the soil for watering of agricultural plants, trees, and the like. A composite underground watering element is also included in an embodiment of the invention. The inventive products may also be used as a pad, including a propagation pad, to collect, store, and dispense water-containing-liquids into plant vessels to provide watering of plants. Also included are underground watering of athletic fields and golf course greens, erosion control products and plant root balls having a watering collar.
